Fails to build from sources

After #50 got solved I tried to install the new version. But I can't build pakku from sources:
[peter /tmp ] 1653 $ git clone https://github.com/kitsunyan/pakku.git

[peter /tmp/pakku (master) ✓ ] 1656 $ git checkout v0.14
Note: switching to 'v0.14'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at 8c75dc9 Release 0.14
